Event organizer sending last-minute updates
The venue notifies the organizer of a room change 3 hours before the event starts. The organizer creates a Multisend campaign targeting the attendee group in People. Contacts with mobile numbers receive SMS immediately; international contacts without mobile get email. The message includes the new room number, floor map link, and contact phone for questions. Multisend tracks delivery across both channels in one report, showing which attendees received the update.
Result
Notification reaches 99% of attendees within 2 hours despite varying contact data quality. The organizer identifies undelivered contacts and calls them directly, preventing confusion at check-in.
